Sea Foam® Motor Treatment is a 100% pure petroleum product that safely and effectively cleans internal fuel and oil system components, helping your gasoline or diesel engine run cleaner and more efficiently. Sea Foam® is an EPA-registered product, and will not harm engine components, seals, gaskets, catalytic converters or oxygen sensors.

Sea Foam® liquefies gum and varnish deposits or internal engine contaminants, removing carbon deposits, freeing sticky valve lifters and rings, improving idle quality, pinging and hesitation problems. By using Sea Foam® to eliminate varnish and carbon buildup, mechanics can more accurately diagnose mechanical problems that may exist. That is why Sea Foam® has been so popular with professional mechanics for over 65 years.

As a fuel system additive, Sea Foam® will clean carburetors, fuel injectors, clean carbon, gum and varnish deposits, add lubricity to fuel, stabilize fuel for 2 years and control moisture.
